The Badminton World Federation (BWF) Yonex German Open got underway in Mülheim today with qualifying action at the Innogy Sports Hall.
With matches in the main draws set to begin tomorrow, today those without an automatic right to compete fought for a place in the full event, with four spots available in each draw.
In the men's singles those to make it through today's action were Malaysia's Joo Ven Soong, Frenchman Thomas Rouxel, Denmark's Rasmus Messerschmidt and Chinese Taipei's Chia Hung Lu.
Each having to win two matches to make it through, Soong had just about the easiest time of it, winning both of his matches in straight games.
He saw off Azerbaijan's Ade Resky Dwicahyo 23-21, 21-11 and compatriot June Wei Cheam 21-9, 21-14.
Rouxel meanwhile had to battle to get through his matches, eventually beating Singapore's Kean Yew Loh and Finland's Eatu Heino 18-21, 21-16, 21-14 and 21-17, 16-21, 21-19.
On the women's side the four qualifiers are Indonesia's Ruseli Hartawan, Turkey's Aliye Demirbag and Neslihan Yigit and South Korea's Hyo Min Kim.
They each only had to win one match, with Kim the only player to win in straight games.
She beat another Indonesian, Yulia Yosephin Susanto, 21-7, 21-18.
Of the four pairs to make it through men's doubles qualifying, Denmark's team of David Daugaard and Frederik Sogaard made it through by the shortest scoreline of 21-17, 21-14 against Chinese Taipei's Ko-Chi Chang and Li Wei Po.
In the women's doubles Debora Jille and Imke Van Der Aar made it through without having to play when Germany's Linda Efler and Isabel Herttrich withdrew.
Another Dutch pair also made it through mixed doubles qualifying without having to play.
Robin Tabeling and Selena Piek did not have to pick up a racket thanks to a withdrawal from Canada's Nyl Yakura and Kristen Tsai.
Tomorrow main draw action will start at 9am local time in the BWF World Tour Super 300 event.
